Summary: This study aimed to prepare antimicrobial nanocomposites consisting of alginate, chitosan, and camptothecin. The results showed a strong chemical interaction between alginate and chitosan, and successful loading of camptothecin in both Ca-Alg(2)/CPT and Ca-Alg(2)-CH/CPT nanomaterials. Antimicrobial tests revealed that Ca-Alg(2)-CH/CPT nanocomposite was more effective against Escherichia coli and Klebsiella pneumoniae, while Ca-Alg(2)/CPT was less efficient in killing all three types of bacteria. PCR analysis indicated changes in bacterial genetic material due to the nanomaterial processing.

Summary: This study investigates the impact of calcium ions on the survival rate of probiotics encapsulated in alginate hydrogel. The results show that the freeze-drying survival rate of Lactobacillus rhamnosus GG (LGG) encapsulated in calcium alginate is lower compared to sodium alginate. The loss of survival mainly occurs during the drying process and is positively correlated with the increase of calcium ions concentration. Calcium ions cause damage to the cell wall/membrane integrity, suppress metabolic activity, and reduce intracellular calcium ion concentration, leading to the loss of probiotic viability.

Summary: This article investigates the mechanism and properties of the gel formation of alginate with different metal ions using nuclear magnetic resonance spectroscopy. The results show that the concentration of calcium and manganese ions does not affect their distribution in the alginate structure and the cross-linking density, while the number of strontium and copper ions affects the number of binding sites and cross-linking density. Therefore, the cross-linking of alginate is mainly influenced by the characteristics of specific ions, with the nature of the bond being less important.

Summary: Despite significant advances in biomaterials-based bone tissue engineering, autografts are still the gold standard for critical-sized bone defects in the OMF region. Most advanced synthetic bone substitutes have not progressed past the preclinical stage due to poor clinical performance and translational barriers, including low scalability, high cost, regulatory restrictions, limited facilities, and human resources.

Summary: This study synthesized biochar based on sapropel and investigated the effects of chemical modification on its textural characteristics, acid-base properties, and adsorption properties. The results showed that the chemical modification increased the fraction of micropores, specific surface area, and changed the surface properties of biochar. The experiment also revealed that biochar pretreated with alkali exhibited the maximum adsorption capacity for copper ions. A conceptual model identifying the mechanisms of copper adsorption on sapropel-based biosorbent was proposed.

Summary: The corrosion inhibitory potency of two new pyrimidine-pyrazole derivatives, PPA and PPC, was evaluated for mild steel in 1 M HCl. The results showed enhanced inhibition activities with increased concentration, reaching maximal values of 91.15% and 92.39% for PPA and PPC, respectively. However, the mitigation potency decreased with increasing temperature. SEM and XPS analysis revealed that PPA and PPC adsorbed on the mild steel surface, forming a shielding layer that prevented the dissolution of the steel in the acidic solution.
